There have been about eleventeen thousand questions across multiple threads on how to calibrate the battery properly...figured it probably should be a sticky in here if possible.
You have to know how to get into Recovery mode. You can do this with Quickboot when the phone is on, or the powered off phone method:
1. Power off phone or pull battery and replace.
2. Hold all three of these buttons down: Vol-Down, Camera button (lower left as you look at the phone) and Power on button).
3. You will see a small graphical menu come up. Most of us are using Clockwork, so I will focus on that - it will be a green menu.
For the battery wipe, Go to Advanced, navigate the menu with the vol up/down keys, and select using the camera button.
There are three ways so far:
The Drain Way:
1. Drain it down until fully dead.
2. Charge normally to full.
3. Reboot to Clockwork recovery and wipe battery stats (under advanced, on second page), reboot phone.
4. Turn everything on, flashlight, Bluetooth, Wi-Fi, Pandora, the whole nine, to quickly drain it completely dead.
5. Charge normally to full.
The Powered Off Charge way:
1. Charge your phone 100% while it’s on
2. Unplug it from the charger, power off, then charge it up to 100% with it in a powered off state.
3. Unplug charger from phone. Power it on, and then charge it to 100% while the phone is on.
4. Unplug the charger and then reboot into Clockwork, go to advanced and clear the battery stats.
5. Power on, charge to full, and then enjoy.
Third option (thanks squshy 7), I paraphrased it and wrote it out a bit for ease.
Maybe we can call it the Mr. Miagi Charge way....aka Power On, Power Off, Charge On, Charge Off way lol
(the parentheses are the state of the phone)
1. Start with the phone powered on.
2. (Phone on) Charge battery until the LED turns blue
3. (Phone on) Unplug the phone from the charger, wait until the LED turns off
4. Power off the phone.
5. (Phone off) Plug the adapter into the phone, charge it up until the LED turns blue
6. (Phone off) Unplug, wait until the LED turns off
7. Power the phone on.
8. Wait until the phone is booted back up all the way, and then power it off again
9. (Phone off) Plug the adapter into the phone, charge it up until the LED turns blue.
10. Boot the phone into recovery mode
11. Go to Advanced, and then choose Wipe Battery Stats.
12. Power the phone on and use normally.
Still a noob, but what would exactly need you to have to Calibrate Battery? Also what exactly does it do for the user?
P.S I'm sure I could look this up but it would be nice to see it in your thread for others to see

Well it's really a matter of semantics...you're not calibrating the battery, per say...it's actually calibrating how android is reading the battery. (these phones use Li-ion batteries, which don't use memory, so they themselves never actually need "calibrated" like some older types of rechargeables)
But...as far as what this means to you, its kind of a big deal! It improves battery life in letting android know when your battery is actually at 100%. When flashing new kernels and ROMs, its very likely that the phone will read your battery at full, when in reality its probably less. So it would seem like your phone isn't getting as good battery life (when in actuality it just hasn't been charged fully but you don't know that because android reads it as full because it hasn't been calibrated )
also, without a calibration, you might notice your battery gauge draining oddly...for example, you might see it quickly drop from 100 to 89, then drop steadily to 72, and then hang for a while at 71 (these are all just made up numbers)
so it means alot! but everybody has different methods and i've never seen anything officially released by spring or samsung to confirm methods...
I will say this though...I've read plenty about how since these Li-ion batteries don't have memory, the DRAINING method, while maybe correctly calibrating your battery, actually HURT the long-term life of your battery.
so heres what ive always done:
(the parentheses are the state of the phone)
(phone on) charge battery till LED blue
(phone on) unplug, wait till LED off
[POWER OFF]
(phone off) plug in, wait till LED blue
(phone off) Unplug, wait till LED off
[POWER ON]
When completely booted, power off again
(phone off) plug in wait till LED blue,
boot into recovery, wipe battery stats
unplug, reboot phone and use
it's always worked so try it out
Actually I'm pretty sure it doesn't fully charge to prevent over charge.. and the whole deal with you guys chargings 2-3 times after the light turns blue is just killing the life of your battery.

My question why is this in devolpment?
Fyi: both methos work but the complete drain does kill battery life. The pluging in multiable times dont. Android nows wheb to stop charging the battery to prevent over charge.

With my battery because I've done the above procedure and my battery doesn't even last 5 hours. Its starting to get annoying. Any ideas?

If it can stop at 92 percent to prevent overcharging, then it can do the same thing when it reaches 100 percent, no matter how many times you plug it in.
I don't know of many, if any li ion battery packs made today that don't have circuitry in them that prevents overcharging.
I put it in development because when you load roms, generally battery is a big concern. I cant tell you how many times ive searched for the same topic all over, I just figured it would be as helpful to others as it would have been to me had it been here and been a stickie at the top.
I've always thought battery calibration was more of a placebo effect, but I have no data either way. On a related note, here's an interesting article about battery stats and charging that was posted a week or so ago:
Android Police: Your Battery Gauge is Lying to You...
Having a battery keep at a full 100% for a long time is not good for li-on batteries. The 10% between 90 and 100% is basically used as a safety buffer. That's why the charge drops between 100 and 90 is much faster than the drops from 80 to 0. even though there ways to increase the actual capacity of the battery by using the methods above, you will still see a quicker drop from full to 90 almost instantly after unplugging the charger. I am in no way saying that those methods don't work in helping the phone read the actual charge of the battery, but they do help increase capacity a little bit. by rearranging the electrons in the battery. There actually is an article on google and on xda that backs it up. I'll try finding it

Lol.. wow alright.
Yes COMPLETELY draining a battery is really bad for a battery; infact if you do so you may end up with a 'bricked' battery.
But the phone also knows not to 'over drain' so with the method of clearing batt stats there's no harm done..actually. allowing your phone to die before charging is healthier than plugging it in before it dies.
I won't argue on the other note anymore; well simply because I don't know enough to continue just know I won't be taking that path
Sent from my SPH-D700 using XDA App
Thanks for the response. But also if you have a separate charger because you have multiple batteries, do you need to have to go through any of this? Or will the charger charge them to their true full state?
It will charge them to 100%. You'll notice it holds 100% for a lot longer.
Sent from my SPH-P100 using Tapatalk
The only thing that needs to be done to calibrate the battery is either flash at full charge or charge to full then delete batterystats, all this drain to dead and charge this way and that is pointless, though u will all argue otherwise, pointlessy

Yes thank you very much! I'm gonna give this a shot probably tonight after the Christmas Eve service and see what happens.
You should definitely add that NONE of this matters if your first usages out of the battery aren't proper. When you get the phone, you need to kill the battery before charging.. charge for 10-12 hours w/the phone off or in a dock, kill battery.. repeat 2 more times to condition the battery physically.
When I'm charging the banker battery, the notification will go green so I think its fully charged. But I've noticed that when I unhook the cable and use the phone for a while, then plug it back in, the notification light lights green. So I'm wondering, does the light turn green for the banker battery at a certain level even though its not fully charged?
Should I let it sit on the charger a couple more hours after the light turns green?

Charge it til it turns green, then turn the device off and charge it for another hour with it being off and it will be fully charged. This is known as bump charging, but does decrease the long-term life of your battery if it is done too often.

+1 to that!
try this: charge battery until the LED turns green. Unplug & then wait until your battery is no longer showing 100% before you try to plug it back in. Mine will show 100% for a while before going down in percentage.
I thought android phones showed green at some point in the 90 percentile range? So if your at 98% it will still be green.
From what I understand because of the old battery the phone thinks that the capacity of current battery is the same. So unless you rooted your phone and wiped battery stats, you are not reaching the full potential of your battery. Unless you turn off your phone and let the hardware judge when the battery is full.
MODS PLEASE DELETE THIS IF YOU WANT ONCE VERIFIED
Basically i had 90 percent BAttery
I switched off the phone, Took out the battery to be sure it is completely turned off.
Plugged in my charger (im charging via PC at the moment, will test with wall charger later)
The LED Came on and then went out after 2 seconds
After ten minutes i took out the battery again and reinserted and powered on
My battery was 100 PERCENT
use battery indicator from market to check your current level or you can check it using *#*#4636#*#* and clicking battery information
Can you please check this. and post here ASAP.
Make sure your battery isnt fully charged (between 20 and 80 percent ideal), Turn off completely (pull the battery out and reinsert if you want to be sure)
Plug in your charger now
After 15 minutes
Take out battery and reinsert.
POWER ON
What is you battery now?
please post your before and after percentage here. THANKS
Mine too.
After CMW and S-Off it is not charging, same behavior. And my battery if fully discharged, which means I bricked my device since I just can't turn it on nor charge it...

You can either let a friend charge your battery for you in his phone
Or
You can get a usb cable, any kind really, chop off the end that goes into the phone. There will be 4 wires exposed, you only need the red and black ones, pay no attention to the green or white wires or whatever color they are. Connect the exposed wire to the battery (to part that touches the prongs on the phone) and it will charge. All you have to do is find out on the web which of the 4 slots on the battery do what, and connect the positive (red) cable to the positive slot on the battery, and the black cable to the neg part of the battery.
In the worst case,you could charge your battery outside the phone with a power supply...
Not an easy way,especially if you're going on vacation...But it's a good thing to be aware from this!
Edit: Durps,you killed me!
my phone charge while off i see alot of people are suffering from this but mine still charge while off my led is on
The issue seems to be fixed with the official cwm recovery flashed from within rom manager.
...at least for me.

so do i..wating for the update
phone will charge with working led if you have the new recovery image, v4.0.1.5 is available now and works for sensation.
I bricked!!
I bricked...
My battery was almost 1%, i removed the battery, and now I am f***ed...
None of my friend use HTC Sensation. and i m totally tensed what should i do...
Can anybody confirm if sensations battery is comatiable with Desire HD??

walk into a phone shop, ask them if u can charge your battery for 10 mins in one of their phones.
Say something about software crash blah blah, they usually dont care at all, and will let you.
PS to confirm is version v4.0.1.5 the good one? ie will let you use/charge your phone in the "normal" way?
update your versions of rom manager ...the dev updated the recovery and now it does charge
Just install the new CWM version 4.0.1.5 from ROM Manager to fix this (HUGE) bug
hello
just to say that with ClockworkMod 4.0.1.5 the phone dont charge the battery when is power off.
thanks
EDIT:
tried to charge with phone off, and work. (with some energy on battery)
but i did had the problem, because i drain the battery to ZERO, and with ZERO battery couldn't charge
Mine does. I did it last night. I drained my new battery dry. And charged it last night with power off because I couldnt even turn it on the battery was so dead. Woke up this morning to a fully charged battery.
My phone does it too.
Same here, mines fine
Keep fastboot checked!!!
+4 works fine here.
OP, please change the title of your thread to "doesn't work for ME (or some people)" as it is misleading.

Defeats the point of wanting to turn the phone off. I prefer to turn it off when I tell it to! Having said that, I never turn my phone off so isn't an issue
+5, works for me too.
didnt work for me...
I drained my battery completely, when I plug it in, the led flashing 11 times last 3 flashes are slow then goes dark.
put it 8h on wall charger, and didnt work...
i had to use this --> http://forum.xda-developers.com/showthread.php?t=1198585
This just happened to me. Kept blinking heaps. So unplugged phone, boot it and instantly plugged in charger and worked after.

I just had my phone at 73% and powered it off and even booted into HBOOT to make sure it was off then pulled the battery. Plugged it in and the orange light came on and stayed on for a bit. I then pulled it after about 10 minutes and powered up the phone, and I was up to 84%
Why do so many people insist on charging the phone while its off? I've never understood this.I have had many devices and have NEVER powered them off to charge, never had to replace any batteries either?

I think its because it charges faster when its off. (idk it could be placebo ) I only charge mine when it is off when it dies. So is it safe to say that the issue is fixed ?

Yeah. I think it does charges but then theres no light. and you can't turn it on while it's plugged in ):
I've never let my battery die tbh, Always carry a 10cm micro usb lead with me as i always have access to a usb port
I did last night on purpose because I am testing an after market battery.
I let my battery died completely last night. When i charge it, it just blink like 5 times, and stopped. So i took off the battery and use a different charger to charge it. The orange light turned on for like 5 sec and disappeared. I thought it just need a little charge. I left the charge overnight. I tried to turn on the phone when i woke up, but it didnt work. I took the cable off, then take out battery and pput it back in. And the phone turns on and fully charged. So I guess the phone does charge, but the indicator light is not just working.

Hello !
I've bought it today so I used it and decided to empty the battery before using it.
After it powers out, I plug it in on computer, pressed the power button and was a big empty battery with " 0%" so I let it charge and now I can't boot up..
Has anyone had the same problem ?
Thanks

plug it in and hold the power button for 2-3minutes. the white led should blink a couple of times. if it does, leave the phone charging for an hour and than unplug it and power it up holding power button.
I've found this solution yesterday, but thanks !
Just a tip
By the way you shouldn't have done empty your battery the first time.
Why ? Because now in our smartphones we have Lithium-Ion battery instead of lead battery so what you did was a good thing ... but for the lead one. When you have a new laptop or smartphone it is already charged up to 40% because if it's below with the natural capacity loss of your battery you could damage the internal circuit and if it is full charged it will be as harmful as if it's not enough charged.
If you empty your battery the first time before using it you can lost 20-25% of its capacity in just one cycle
So when you have a new smartphone or laptop or anything else with a Litium battery :
- Full charge it before using it
- Discharge it until the warning message "Plug your phone ..."
- Full charge it again
And never empty your battery, keep in mind that there is a complex circuit system which always need electricity.
These informations are from a very very good pdf i read few months ago about Lithium-Ion batteries. Unfortunately it's full french but if someone is interested I can send him a PM with the link
